RIDDLE.

SPECIFICATION formingpart of Letters Patent No. 706,061, dated August 5, 1902. Application filed December 30, 1901. Serial No. 87,669. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD zen of the United States,residing at Mariomin the county of Marion and State of Ohio, have invented certain new and useful Improvements in Riddles, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to riddles, and has for its object to produce a riddle for cleaning grain which is adapted for successful operation in cleaning diiferent kinds and sizes of grain, both in small or large bulk.

To these ends myinvention consists in certain novel features, which I will now proceed to describe and will then particularly point out in the claims.

In the accompanying drawings, Figure l is a plan view of a riddle embodying my invention in one form. Fig. 2 is a longitudinal sectional view of the same, taken on the line no a: of Fig. 1 and looking in the direction of the arrows; and Fig. 3 is a transverse sec tional view of the same, taken on the line y y of Fig. 2 and looking in the direction of the arrows.

In the said drawings, 1 indicates the supporting-frame of the riddle, which may be of any suitable construction.

The body or working portion of the riddle is preferably constructed of a single sheet of metal and comprises a plurality of 'inclined slats 2, preferably imperforate, their inclination being upward and rearward away from the receiving end of the riddle and the lower edge of each slat lying under or practically under the upper edge of the preceding slat. The lower edge of each slat is connected with the upper edge of the preceding slat by a plurality of upright bars 3, separated by suitable intervals, so as to form spaces or openings 4 of a height equal to the distance between the adjacent edges of the slats and of a width about three times that of the bars, these proportions being those which I prefer. From the lower edge of each slat there extends upward within each spaced at the center thereof a projection 5 to about mid-height of said opening, these projections forming a comb along the lower edge of the slat and there being spaces between the projections and bars about equal to the width of said projections HUBER, a citikept out of the grain.

and bars, which are themselves preferably of about equal width. It will thus be seen that the upright or vertical portions of the riddle are provided with. a plurality of comparatively narrow openings along their lower portions and with a plurality of larger openings along their upper portions. In operating upon small grain and in smallbulk the grain will pass only through the narrower openings between the projections and bars along the lower edges of the slats, and rubbish or particles larger than these narrow lower openings will be thrown backward by the blast and agitation of the riddle, which Will be vibrated in the usual manner, so that said rubbish and particles will be Worked out over the riddle and out of the mill, being thus When cleaning'large grain and in large bulk, the grain will pass through the larger openings above the comb; but the blast coming through these openings will blow back-the lighter parts of the rubbish and the lighter particles, while the heavier and larger particles will Work down to the lower edges of the slats under the grain and will be arrested by the comb, or, in other words, by the lower portions of the bars and by the projections and will be ultimately thrown out by the combined action of the blast and the agitation of the riddle. It will thus be seen that by reason of the construction which I have devised both large and small grain in large and small bulk can be conveniently separated from and cleaned .of

.foreign matter.

I do not wish to be understood as limiting myself to the precise details of construction hereinbefore described, and shown in the accompanying drawings, as it is obvious that these details may be modified without departing from the principle of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A riddle for cleaning grain, comprising inclined slats, bars extending from the lower edge of each slat to the upper edge of the preceding slat, and projections between the bars, extending upward from the lower edge of each slat into the opening formed between the ad jacent bars, substantially as described.

2. A riddle for cleaning grain, comprising and a plurality of relatively wider openings to above the same and above the projections,

substantially as described.

In testimony whereof I affix my signaturein presence of two witnesses.
